I've ever read history that 1 gambler able win $ 250.000 with math , maybe at range 1900++
It's amazing right ? but for this digital era, it's quite difficult to make it happen since the system getting complicated from time to time
Everyone with little dose of luck and very large bankroll can do that. Very large bets are required to win 250000$, theoretically you can put million dollars and roll dice on 1.25X and there you go - 250000$. Math? No, he could have lost. He was lucky enough to roll his numbers.
Behind that story is probably link to casino or perhaps referral link

Maths can help you calculate your wins and also with a personal audit f your gambling life but it will not make you win games because you are good with numbers, NO! it doesn't work that way and so it is best if you can plan and manage your personal life and emotions before embarking on the journey of gambling.
